GREEN COFFEE BEAN EXTRACT
Green coffee beans are coffee beans in their raw, unroasted state. There are two key compounds in unroasted coffee beans: caffeic acid and chlorogenic acid. The chlorogenic acid and caffeic acid in GCBE have been clinically studied and preliminary research suggests that they have several beneficial effects on weight loss.
Studies suggest that GCBE inhibits fatty acid synthase, increased fat oxidation and promotes increased metabolism. There have been several human studies on Green Coffee Bean Extract.
These studies are so-called randomized controlled trials, which are the gold standard of scientific experiments in humans.
One of them included 30 overweight individuals and went on for 12 weeks. There were two groups… one consumed regular Instant coffee, while the other consumed Instant coffee enriched with 200 mg of Green Coffee Bean Extract (See Study).
As you can see, the group taking the instant coffee with green coffee bean extract lost 11.9 pounds (5.4 kg), while the group taking plain instant coffee lost only 3.7 pounds (1.7 kg).
Body fat percentage also went down by 3.6% in the green coffee extract group, compared to 0.7% in the other group.
Neither group was instructed to change their diet or exercise habits.
